Answer:
New cells are naive to the infectious cells who attack it or they are not well prepared to deal with the different scenarios. But, the cells who are attacked before has the set or sequence of the viral or bacterial genome strand been identified by them, which leads to more safety or protection from these foreign bodies.
Explanation:
- Mechanism To attack a host cell:
The viruses and other infectious material enters and attacks the host cell, by breaching its membrane wall and installing or leaving a gene of its own inside the cell. Which then combines with the genome of the cell and it goes through the process of replication, translation etc,along with the host cell machinery. Which then spreads the specific gene strand more in the environment
- <u>Camouflage obtained by the infectious cell to hide it self:</u>
After the genome enters the host cell at first it does not recognizes the strands or foreign cells, as they cover there body with a camouflage sort of membrane and they look more like the body cells.
- <u>Reactions by the host cell and as a whole the body:</u>
The organisms detects the genome of the infections cells or strand, as they store the data about it in its server or database. As if the next time they were under attack then precautions will be there by the host cell to deal with it.
As for the cell who are never attacked before will be less safe to deal with these foreign bodies.
Explanation:
In digestion, the liver is involved in processing the nutrients that are absorbed from the small intestine. It helps in the digestion of fat.
On the other hand, the liver maintains homeostasis by serving an important function in the excretory system.
Answer:
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.
Explanation:
Answer:
This is because the cell membrane is a partially permeable membrane, hence allowing the smaller molecules to enter it and larger molecules to be out. For example, protein is too large to enter the cell
Explanation:
Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are Gonadotropins stimulated in the gonads. In females, they are located in the ovaries. They are not needed for life yet important for reproduction. Progesterone which is being secreted in corpus luteum is needed for maintenance of pregnancy thus if a female has a low FSH and LH it will affect the chance of her be pregnant.
